WICKHAM: NEW MIOCENE COLEOPTERA FROM FLORISSANT. 439 



mined, surface roughened but without definable sculpture. Elytra 

 simply rounded at apices, surface with very poorly preserved sculpture 

 of striae which are moderately coarsely and closely punctured in single 

 series. Legs partly displaced and nowhere fully displayed but what 

 can be seen indicates that they are moderately stout for this genus. 

 Length, as preserved, 23.60 mm., in life undoubtedly a little less since 

 the body of the fossil had been distended by maceration. 



Described from one specimen. 



Type. No. 2,470 M. C. Z. Florissant, Col. (No. 8,890 S. H. Scud- 

 derColl.). 



My chief reason for referring this fossil to Buprestis rather than to 

 Chalcophora or Dicerca is to be found in the nature of the elytral sculp- 

 ture, since true generic characters are wanting. It is the largest of 

 the Buprestidae from the Florissant shales, but unfortunately is not 

 at all well preserved. Nevertheless it is easily recognizable at sight 

 as a member of this family. Most likely it lived upon the pines which 

 abounded on the shores of Lake Florissant. 



BUPRESTIS SCUDDERI, sp. nov. 

 Plate 3, fig. 3. 



Form only moderately elongate or even somewhat stout. Head 

 large, front with a deep indentation having a raised center, the re- 

 mainder of the surface with fine crowded granules in fairly high relief. 

 Prothorax about one and one half times as wide as long, sides appar- 

 ently imperfect but, as preserved, nearly straight as if the thoracic 

 apex and base were about equal. Basal margin sinuate each side. 

 Pronotum covered with moderately closely set granules, more crowded 

 towards the sides, rounded like those of the head but a little coarser 

 and less in relief. Longitudinal median line present, not deep and 

 possibly adventitious. Elytra sinuate along the exterior margin, 

 truncate at apex, surface with very fine, sharp, crenulate raised lines 

 representing punctured striae, the intervening spaces granulate in 

 more than one series. Legs wanting. Length, to elytral tip, 18.50 

 mm., in life about 2 mm. less; of elytron, 10.75 mm. Width of pro- 

 thorax, 5.50 mm. 



Described from one specimen.
